SASH FASTENER.

SPECIFICATION forming part of Letters Patent No. 695,263, dated March 11, 1902.

Application filed June 15, 1901. Serial No. 64,665. (No model.)

To all whom, it may concern.-

Be it known that I, VVILLAM ROLLINs ABRAMS, a citizen of the United States, and a resident of Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved Sash-Fastener, of which the following is a full, clear, and exact description.

This invention relates to a device for his tening window-sashes adj ustably together; and it comprises a bolt arranged to engage the sash and controlled by a peculiarly-formed lever having connection with the bolt to throw the bolt from one position to the other.

This specification is a specific description of several forms of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the invention, showing the bolt engaged. Fig. 2 is a plan view of the same. Fig. 3 is a side view. Fig. 4 is a detail perspective view of a slightly-modified form of the bolt. Fig. 5 is a rear elevation of a modified form of lever. Fig.6 is a sectional elevation showing a slight modification in the form of the ratchet-plate. Fig. 7 is a plan View illustrating a modification in the manner of actuating the lever,

- and Fig. 8 is a perspective view of the same construction. 7

Referring to Figs. 1, 2, and 3, a indicates the lower sash, and a the upper sash. The upper sash a carries a vertically-disposed plate b,with shoulders Z) struck up therefrom, such shoulders forming ratchet-teeth adapted to be engaged by a bolt 0, carried in guides d on a base-plate d, fastened to the sash a. This bolt 0 is movable toward and from the ratchet-plate b, so as to lock the sashes together or release them, as desired. For operating the bolt I employ a bent fingerlever comprising arms e and c. This lever is fulcrumed in bearings (7. through the medium of trunnions eiformed on the lever at the bend therein. The arm 6 of the lever is adapted to be engaged by the finger of the operator, and

when the bolt 0 is in active position this arm stands vertically. The arm e is provided with a laterally-projected stud 6 which fits loosely in a transverse slot 0', formed in the bolt 0. A spring f presses the finger-lever and tends to hold it in the active position. By moving backward the arm 6 of the fingerlever the projection e is caused to ride through the slot 0' and to throw the bolt backward to inactive position. This releases the lock between the sashes. The instant that the finger-lever is released the spring f asserts itself and returns the parts to their active positions. If desired, a cord or the like may be attached to the arm e of the finger-lever, so as to permit operating the finger without necessitating actually grasping it.

In Fig. 4. I have illustrated a modification in the bolt 0, in which the slot therein comprises a transverse portion 0 and a diagonal portion 0 The transverse portion 0 receives the projection e when the bolt is in locked position and prevents the retraction of the bolt except upon the operation of the fingerlever, and when the lever is actuated the projection e slides through the inclined portion 0 of the slot and throws the bolt. By making this part of the slot inclined or diagonally disposed, as described, the bolt is given a greater throw in proportion to the length of the slot than when the slot is made straight and transversely disposed, as in Figs. 1, 2, and 8.

If desired, the arm 6 of the finger-lever may be formed with a stud e, as shown in Fig. 5, such stud taking the place of the stud or projection e in Figs. 1, 2, and 3. This will act on the bolt in the same manner; but it should be understood that in this case the position of the slot 0 in the bolt will have to be changed to correspond with the change in the location of the stud.

Fig. 6 shows a slight modification of the plate I) in Figs. 1, 2, and 3 in that the plate instead of being provided with tapering shoulders or teeth I) is provided with relatively abrupt shoulders or ribs b the purpose of which is to prevent the bolt from sliding on the plate and from riding up the inclined surfaces leading to the shoulders Z) in Figs. 1, 2, and 3.

Figs. 7 and 8 illustrate a modification of the Various changes in the form, proportions,

and minor details of my invention may be resorted to Without departing from the spirit and scope of myjinvention. Hence I consider myself entitled to all such variations as may liewithin the scope of my claims.

Having thus. described my invention, I

claim as new and desire to secure by Letters Patent- 1. A sash-fastener, comprising a bolt, a finger-lever arrangedtothrow the bolt, the finger-lever having a projection extending laterally from the axis of its fulcrum, and a spring bearing on said projection to hold the lever in either one of two positions.

2. The combination of alongitudinally-sliding bolt having a groove formed in one side face thereof, a finger-lever lying alongside of the bolt and having its fulcrum disposed transversely thereof, said lever having apart playing loosely in the groove of the bolt, for the purpose specified.

3. The combination of a longitudinally-sliding bolt having a groove formed in one side face thereof, a finger-lever lying alongside of the bolt and having its fulcrum disposed transversely thereof, said lever having a part playing loosely in the groove of the bolt, and the groove in the bolt havingapartrunning transversely therewith and leading into a diagonally-disposed part, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
